The categories don't exist (Baker)

There's no either-or division with poems. What's made up and what's not made up? What's the varnished truth, what's the unvarnished truth? We don't care. With prose you first want to know: Is it fiction, is it nonfiction? Everything follows from that. The books go in different places in the bookstore. But we don't do that with poems, or with song lyrics. Books of poems go straight to the poetry section. There's no nonfictional poetry and fictional poetry. The categories don't exist.

Nicholson Baker, from The Anthologist
